What is Reverse Phone Lookup?

A reverse phone lookup is a simple search that’s done by phone number rather than name. YouMail maintains the industry’s foremost collection of phone numbers and it’s free for anyone to search.

Our patented technology allows us to track behavior patterns, find people that abuse the Telephone Network, and prevent those calls from reaching our users. By doing a reverse phone lookup, you can search our comprehensive database to find out who is calling you or if that unfamiliar number has a history of placing potentially illegal or unwanted calls.
